stride
First measure your inseam. If the measurement is within the green bar, the model fits you.
How to measure your stride length
Take a book and stand with your back to the wall. Clamp the book between your legs. Pull it into your crotch, as if sitting on a saddle. Hold the book parallel to the floor along the wall behind you. Make a line on the wall behind you/top edge of the book. Now measure the distance to the floor. Please take the measurements with your shoes on.
If you choose a bike with a top tube, make sure that the height of the top tube is equal to or less than your inseam (see picture).
